concern f; I ffBe it knownthatfl, EzRAFAifRnEY, of

*Mount Morris, *in 1 thelcounty of. Ogle and Stat-e of Illinois,"haveinvented "a new and useful Imprqvemene in Hominy Machines inyimachineconstructed with improvement. 2, is: avertical transverse sec- Similar letters ofrefelefiee indicate corresponding parts in the several figures.

My improvement relates particularly to fthat description ofmachine whichernploys der such machines capable of self feeding and self discharging, and for retaining within them forgadefinite time a certain of corn to becjrushedor beaten into arranged over the-inlet or feed passage and the other under the outlet or discharge passage in the bottomof the cylinder, said slides being arranged in such relation to two I cams arranged a short distance apart on the 3} face of a wheel which has a slower motion than the beater shaft, that at every revolution of said wheel they are both operated wand caused to open said feed and discharge a passages one after the other, the discharge 1 passage being openedi first by the forward cam, and owing Itothe slow motion of the wheel on which saidicamfis arranged is kept openuntil the contents of the cylinder havefescaped,when or as soon as the cam escapes by the slide, itwill, by the action of a spring on the slide, be closed whereupon the feed passage will be opened by the rear cam and owingto the a slow motion of the wheel onwhich this cam is arranged will be kept open sufliciently long to allow the proper quantity of corn toflbe cracked at one operation,to pass into thecylinder, as soon as which occurs, the cam escapes by the slide :ftndd allows it to adjust itself and. out off the ee 1 a a feed passage G, and

f this improvement, the necessity of emplo-ying an-attendant, to watch the machine and feed itat proper intervals and also discharge the hominy as fast "as prepared, is

avoided. It only being necessary to provide g "alarge hopper filled with corn, above a ma- ,chine my improvement and set the machinein motion and itwill feed and discha'rgeitself atproper intervals in a" more ltended by a personr To enable others skilled in the art to make and use my invention, I will proceedto de- "sc" ribe its construction and operation. a

1 A, represents the cracking or breaking rangedywithin the same; C, the hopper .placed over. the cylinder and having a hole D,.in its: bottom, charge spout.

and E,-the inclined dis- F, F,are the slides and G, H, the feed and discharge passages in the cylinder, the slide F, serves for opening and closing the F, the discharge passage H, which extends along the entire length of the cylinder; this slide is provided with a passage. corresponding to H, and is connected directly to a spring I, which is attached at m, to an arm I), as shown, and the slide F, is made solid and is also connected through an arm 0, to a spring J. The springs I, J render the slides self adjusting.

K, K, are the cams on the face of the wheel L; these cams are placed out of line with one another so as to be in line with the slides or arms, 6, c, by which the slides are operated, and behind each other so as to come alternately in cont-act with the arms of the slides as shown in Figs. 1, 2 and 3.

M, represents a band leading from a pulley on the driving shaft N, for giving a rapid motion to the shaft of breakers or beaters, and O, a band running from a pulley on a screw wheel shaft P, for giving a slow motion to the cam wheel L. Q is a worm on the driving shaft for giving motion through the screw wheel R, to the cam wheel shaft P, as will be evident from the drawing.

The operation of the slides is as follows: The hopper is filled with corn and the machine set in motion. As soon as the cam wheel makes one or a part of a revolution according to the positions of the cams, the cam K, comes in cont-act with the slide F, and gradually forces it from the position perfect and'regular manner than when at: a

cylinder. B, the shaft of radial heaters ari shown in black to the position shown in red in Fig. 2, and thereby opens the discharge and lets out whatever may be in the cylinder, this being done, in a few seconds the cam escapes by the slide and allows it by the aid of the spring J, to adjust itself to its original position and thereby close the discharge; the cam K, now comes in contact with the slide E, and opens it in a similar manner as illustrated in red in Figs. 1 and 2, and allows a sufficient supply of corn from the hopper to be cracked at one operation to pass into the cylinder; by the time the proper quantity has been fed into the cylinder, the cam escapes by the slide and allows it to assume its original position and consequently to shut off the feed. The corn fed into the cylinder is operated upon until the cams again come in contact with the slides which does not occur until the corn has been sufliciently cracked, owing to the cam wheel being driven by a screw which turns it very slowly. lVhen the cams do again come into operative position, K, opens, the discharge first, and lets out the hominy and then escapes and allows the slide to adjust itself and close the discharge, and K next opens the feed passage and lets in a fresh supply of corn and then escapes and allows the slide to adjust itself and shut oif the feed; thus the operation proceeds, in the most perfect and regular manner without requiring an attendant.

I do not claim the self acting slides, E, F, separately nor the wheel L, with cams for operating the same as these devices are well known as the feed movement of grain mills, seed planters, etc., etc. But

What I do claim as my invention and desire to secure by Letters Patent, is-

The employment of the two self adjusting slides E, F, with the two cams K, K, arranged a short distance apart on a wheel having a slower motion than the beater shaft essentially as shown and described, and for the purpose as set forth.
